# Industrial Specification: Case Forming and Drawing Press

## 1. Technical Definition
A specialized press machine that forms and draws metal blanks into cartridge cases through progressive stamping and deep drawing operations.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **25-80 MPa forming pressure, 0.5-3.0 mm/s drawing speed, 150-300°C working temperature**. Failure boundary: **Material yield strength exceedance at 450 MPa for steel tooling, punch deflection exceeding 0.05 mm tolerance, blank holder force deviation beyond ±7.5%**, Mechanism: **Lüders band formation during deep drawing causing localized necking, adiabatic shear band development at punch radius due to strain rate sensitivity (m=0.02 for cartridge brass), springback exceeding 0.3° angular deviation**.

### 2.1 Analytical Physics Model
Governed by the **Thin-Wall Pressure Vessel Stress Analysis**:

> **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$  
> **Engineering Impact**: Determines the hoop stress boundary to prevent rupture.
